Specifies the connection to the X server.
event_mask
Specifies the event mask.
event_return
Returns the matched event's associated structure.

event_type

DESCRIPTION
The
function copies the first event from the event queue into the specified
structure and then removes it from the queue.
If the event queue is empty,
flushes the output buffer and blocks until an event is received.
The
function returns the first event from the event queue,
but it does not remove the event from the queue.
If the queue is empty,
flushes the output buffer and blocks until an event is received.
It then copies the event into the client-supplied
structure without removing it from the event queue.
The
function searches the event queue for an event that matches both the specified
window and event mask.
When it finds a match,
removes that event from the queue and copies it into the specified
structure.
The other events stored in the queue are not discarded.
If a matching event is not in the queue,
flushes the output buffer and blocks until one is received.
The
function searches the event queue and then the events available
on the server connection for the first event that matches the specified window
and event mask.
If it finds a match,
removes that event, copies it into the specified
structure, and returns
The other events stored in the queue are not discarded.
If the event you requested is not available,
returns
and the output buffer will have been flushed.
The
function searches the event queue for the events associated with the
specified mask.
When it finds a match,
removes that event and copies it into the specified
structure.
The other events stored in the queue are not discarded.
If the event you requested is not in the queue,
flushes the output buffer and blocks until one is received.
The
function searches the event queue and then any events available on the
server connection for the first event that matches the specified mask.
If it finds a match,
removes that event, copies it into the specified
structure, and returns
The other events stored in the queue are not discarded.
If the event you requested is not available,
returns
and the output buffer will have been flushed.
The
function searches the event queue and then any events available
on the server connection for the first event that matches the specified type.
If it finds a match,
removes that event, copies it into the specified
structure, and returns
The other events in the queue are not discarded.
If the event is not available,
returns
and the output buffer will have been flushed.
The
function searches the event queue and then any events available
on the server connection for the first event that matches the specified
type and window.
If it finds a match,
removes the event from the queue, copies it into the specified
structure, and returns
The other events in the queue are not discarded.
If the event is not available,
returns
and the output buffer will have been flushed.
